which allows you to set the charge current accurately, 
then the battery should always be recharged using the 
“normal” charge rate of 1/10C; see the example stated 
above.
Wherever possible, transmitter batteries should 
always be recharged at the 1/10C rate, in order to 
avoid differences in cell states. The charge current 
must never exceed the maximum permissible value 
stated in the transmitter instructions.

If your battery charger includes the facility to adjust 

• 

the Delta Peak charge cut-off voltage, set this value 
to 5 mV per cell. However, most chargers are set to 
a fi xed cut-off value of 15 … 20 mV per cell, which 
makes them suitable for use with both NiCd and 
NiMH batteries. If you are not sure about this, please 
refer to the operating instructions supplied with your 
charger, or ask at your local model shop whether 
your charger is also suitable for Ni-MH packs. If in 
any doubt, charge your batteries at half the stated 
maximum charge current.

Discharging
All rechargeable batteries sold by Graupner and GM-
Racing are suitable for a maximum continuous current 
load of 6C … 13C, according to battery type (refer to the 
manufacturer’s specifi cation!). The higher the continuous 
current load, the shorter the batteries’ useful life.

Use your battery until its performance falls off, or until 

• 

the low voltage warning is triggered.
Caution:
When stored for a long period, the cell voltage should 
not be allowed to fall below 1.2 V. This means that 
you may have to recharge the battery before sto-

ring it.
Refl ex charging and charge / discharge (cycle) 

• 

programs shorten the effective life of batteries unne-
cessarily, and are only suitable for checking battery 
quality or “reviving” relatively old cells. It also makes 
no sense to charge / discharge a battery before using 
it - unless you simply wish to check its quality.

Disposal of exhausted dry and rechargeable batte-
ries
The German Battery Order places a legal requirement 
on every consumer to return all used and exhausted 
dry cells and rechargeable batteries. It is prohibited to 
dispose of these items in the ordinary domestic waste. 
At no charge to the user, old dry and rechargeable 
batteries can be surrendered at local authority collec-
tion points, Graupner retail outlets, and any other shop 
where dry and rechargeable batteries of the same type 
are sold. You can also send batteries supplied by us to 
the following address - with adequate pre-paid postage 
- for disposal:
Graupner GmbH & Co. KG
Service: Gebrauchte Batterien (Used batteries)
Henriettenstr. 94 - 96
